whats problem

A new valued customer of ours a Mr Mark Pugh fetched his car to us because the car was having DPF issue's that main manufactures were unable to solve. Mr Pugh kindly sent us this message: 

very professional, put themselves out to help me in an emergency. They managed to diagnose and repair the DPF filter plus diagnosed a problem which manufactures could not do.  

I am now a valued customer of AJ Fleetcare.
